title: Neuroradiological examinations in chiasmal syndromes.
abstract: The chiasmal syndrome has distinct ophthalmological findings. However, the pathological processes in the chiasmal region often give rise to differential diagnostic problems. Computer tomography is the neuroradiological method of choice. Besides computer tomography some other neuroradiological examination techniques as skull X-rays, carotid arteriography and in some instances cisternography have retained their position in the diagnosis of space-occupying processes in the region of the chiasm, which will be illustrated.
